1 Applicazione pulizia ad aria compressa. canico, chimico, colorifici, gomme; ed in genere dio grossa granulometria. Application The sleeve filter system is a compressed air dust cleaner. It is used in many industrial sectors: footwear, textiles, mechanical engineering, chemicals, paints, tyres and generally in industries where you need air suction and purification, with average grain size dust. 613

The filter consists of an upper inlet, a central filtering section and a bottom collection part; the scrubbing system is located inside the upper body. The dusty air is sucked through the channels and sent to the bottom (hopper) of the filter or when specifically required into a settling pre-chamber; due to the abrupt reduction in speed, the heavier particles settle while the others are deposited along the cartridges. The filtered air is then expelled into the atmosphere with the pollutants removed. The cleaning of the sleeves is achieved via a jet of compressed air, controlled by an electronic control unit (cyclic programmer) that automatically activates the solenoid controlled valves, thus ensuring the efficiency of the sleeves at the maximum levels.

Elementi filtranti standard). Total Immersion Cleaning Apparatus - Certified compressed air-storage tank - Diaphragm valves complete with solenoid - Perforated pipes with compressed air launch nozzles - Electronic control unit with the possibility of regulating the blow force and pause time - Differential-pressure meter with digital display of measured value. - The cleaning is done only when needed, or when the differential meter detects a determined differential pressure, which instructs the control unit to start cleaning. This system allows compressed air to be saved, reduces the wear and tear on the filter elements and contributes towards savings on running costs.
